HISTORY

  V2.02 (06/28/2000)

      New: Cross-language updates are supported now.

      Fixed: The D-channel Monitor refused to run on a clean Windows 95
             system (with no recent Internet Explorer, Office, etc.
             installed).

      Fixed: The Connection Tester and the Test Wizard were not updated
             if updating an older ISDN Tools installation.

      Fixed: It was impossible to uninstall the ISDN Tools after updating
             an older version or if the setup was started multiple times.

      Fixed: The D-channel Monitor does not clear the display area
             correctly after the log has reached a certain length.

      Changed: Removed installation of CCM and TSP from ISDN Tools.
               They are now installed with the Columbus World software.

      Changed: The installation now checks for files that are in use
               during the setup process and displays a reboot dialog
               if necessary.

  V2.01 (05/15/2000)

      New: The ISDN Tools are now shipped as a self-extracting executable.

      Fixed: It was impossible to install the ISDN Tools on a hard disk
             other than "C:".
